Never in the history of Sierra Leone’s elections have women so actively engaged in politics or competed for parliamentary seats. In the past, women did the dancing and cooking for elections campaigning. In the May 14th elections, we saw over 168 women candidates competitive for President, Vice President and Parliamentary seats.

One would think that about 5% of these women would have emerged as winners. But it was not so, because of our cultural perception of women. We need to change our culture. Women could be active politicians. The Christians in their own way encouraged women to be preachers(传教士) but the Muslim leaders say women should not head for officiating(主持) prayers.

The same happens in certain parts of the country where women are not part of decision taken in male secret societies. This prevents them from achieving some of their goals. A senior head in one of the ministries told me that she was getting problems with some of her staff members especially the male staff. Most women that come from the Northern part of country experience such problems. Some men are saying that a woman cannot be their leader.

Some women are also prejudiced against their women folks. In the last elections, most woman did not support their colleagues. In some parts of the country, because they are not members of secret societies they were not allowed to contest for chieftaincies (酋长或首领的位置). However, Sierra Leones not withstanding the cultural prejudice against women has witnessed women occupying high public offices. They have been appointed to head certain areas.

Sierra Leone is moving from its past culture. We need a change in our culture. Women all over the world are recognized one way or the other as they are now involved in the use of technology. We now see women as air pilots, and they even attempt to go to travel in space.
